Unlocking the Blood Diamond achievement in Payday 2 requires successfully completing the Diamond Heist job while fulfilling specific, hidden criteria related to the map's unique mechanics, puzzle solutions, and stealth or loud execution methods. This guide details the exact prerequisites, step-by-step walkthrough, and rewards associated with the achievement.
Navigating the intricacies of the Diamond Heist in Payday 2 can be a challenging endeavor for both veteran heisters and newcomers alike. Released as part of the Diamond Heist DLC, this job takes players into a high-security museum filled with laser grids, security guards, and complex puzzle mechanics. Among the various challenges, trophies, and achievements tied to this heist, the Blood Diamond achievement stands out as a test of coordination, puzzle-solving speed, and map knowledge. Whether you are attempting this solo with AI bots or coordinating with a full crew of four players, understanding the underlying triggers, timeline requirements, and loot mechanics is essential for securing the achievement without failing halfway through.
Overview of the Diamond Heist and Achievement Prerequisites
Before launching the mission, players must ensure they meet the basic requirements to even trigger the achievement conditions. The Blood Diamond achievement is tied directly to the Diamond Heist job, which can be purchased and hosted by anyone who owns the relevant downloadable content, or joined by any player via the crime.net lobby browser regardless of DLC ownership.
To maximize your chances of unlocking the achievement cleanly, it is recommended to prepare your loadout and crew configuration appropriately. While the heist can technically be completed on any difficulty, certain puzzles require speed and uninterrupted interaction times, making lower difficulties or a well-rehearsed stealth approach preferable for first-time hunters.
Recommended Crew Setup and Loadouts
- Primary Approach: Stealth is heavily recommended to avoid the chaotic onslaught of police assaults while attempting time-sensitive puzzle inputs.
- Skills: Invest in ECM Jammer duration upgrades (Shinobi and Silent Killer trees), faster lockpicking, and cleaner interactions.
- Weapons: Silenced weapons with high concealment to maintain a low detection risk if masks are forced on prematurely.
- Deployables: Dual ECM Jammers are mandatory if your team plans to rush specific objectives or bypass electronic doors without triggering alarms.
Step-by-Step Walkthrough to Unlock Blood Diamond
Achieving the Blood Diamond unlock requires a precise sequence of events starting from the moment you breach the museum and culminating in the extraction phase. While the core objective of the Diamond Heist is to steal the massive diamond artifact from the display room on the upper floor, the secret achievement criteria branch off into specific historical puzzle interactions within the security offices.
Phase 1: Infiltration and Security Control
Upon entering the museum, your immediate priority is neutralizing or avoiding the roaming security guards and civilian witnesses. If you are playing on higher difficulties like Death Wish or Death Sentence, managing pager responses becomes your primary operational bottleneck. You have a maximum of four pager answers before the alarm is automatically raised, meaning any excess guards must be smoothly bypassed rather than killed.
- Locate the Security Room: Search the office cubicles and back rooms to find the security room. Taking out the guard inside allows you to disable select camera feeds, drastically reducing the risk of accidental detection.
- Map the Laser Layout: The upper display room features an intricate web of security lasers. Familiarize yourself with the breaker box locations that can temporarily disable these grids, or practice timing your crouches and jumps through the beams.
Phase 2: Solving the Office Puzzles and Vault Access
The crux of the Blood Diamond achievement revolves around interacting with the CEO's office and executing the computer terminal sequence correctly.
- The Code Inputs: Players must scour the office desks for scattered files containing clues or directly input codes derived from the paintings and artifacts found in the surrounding rooms.
- The Timed Window: Once the vault mechanism is activated, a timer typically initiates. Your team must coordinate to ensure that code inputs on the secondary terminals match the flashing indicators in the security room. Mistakes will reset the puzzle sequence and delay your progress, risking detection if you are playing in stealth.
Phase 3: Securing the Diamond and Triggering the Unlock
Once the vault door swings open, the iconic large diamond rests inside. However, simply bagging the standard loot is not always enough; the Blood Diamond achievement specifically requires you to trigger the alternate event sequence where the diamond is substituted or handled according to the specific trigger parameters coded into the map script.
| Heist Phase | Primary Objective | Potential Risk | Recommended Action |
|---|---|---|---|
| Infiltration | Bypass guards and disable cameras | Pager limit exceeded, premature alarm | Use ECM jammers and coordinate kills |
| Puzzle Solving | Input office computer codes correctly | Incorrect sequence resets timer | Cross-reference room paintings before input |
| Extraction | Escape with the artifact | Police assault wave overwhelming crew | Smoke grenades, flashbangs, and defensive cover |
Common Mistakes and Troubleshooting
Players frequently encounter roadblocks when hunting for the Blood Diamond achievement due to subtle missteps in execution order or timing. Reviewing these common failure points can save hours of repeated restarts.
- Triggering Alarms Too Early: If loud mode is triggered before the vault puzzle is properly initiated, the sheer volume of incoming law enforcement units can interrupt players attempting to interact with the computer terminals. Ensure your crew brings proper crowd-control assets if things go loud.
- Misreading Code Clues: The numbers required for the office terminals change dynamically with every restart. Do not rely on static guides for the codes; always check the specific spawn locations in your current lobby instance.
- Sync Issues in Multiplayer: High latency or desynchronization between the host and client players can sometimes cause puzzle interactions to register incorrectly. If a terminal refuses to accept an input, have the host handle that specific interaction.
Frequently Asked Questions
Do I need to complete the Diamond Heist in stealth to get the Blood Diamond achievement?
While it is technically possible to unlock the achievement while playing in loud mode, doing so is exponentially more difficult due to constant police interference with puzzle terminals. Stealth is strongly advised.
Can I earn this achievement playing solo with AI crew members?
Yes, the achievement can be unlocked in solo play with AI bots. However, because AI cannot interact with complex puzzle terminals or answer pagers, you must handle all stealth mechanics and code inputs entirely by yourself.
Which difficulty level is required for the Blood Diamond achievement?
Payday 2 generally allows achievements to be unlocked on any difficulty unless explicitly stated otherwise in the achievement description. You can run the heist on Normal difficulty to minimize guard awareness and health pools.
What rewards are unlocked alongside the Blood Diamond achievement?
In addition to the achievement completion status on your Steam or console profile, successfully completing the criteria typically grants associated XP, offshore cash, and unlocks specific weapon mods, masks, or patterns tied to the Diamond Heist update.
Final Recommendation
To successfully secure the Blood Diamond achievement, gather a dedicated two-to-four-player crew, equip high-concealment stealth loadouts with dual ECM jammers, and practice the office puzzle sequence on a lower difficulty setting first. Take your time clearing out patrolling guards before interacting with computer terminals, and ensure smooth communication via voice chat to coordinate simultaneous inputs.
